New features and enhancements

Please see the Change Log for a list of new features and enhancements in XJTAG 3.2.

Running XJEase code before the Debug Connection Test

In XJTAG v3.1, the Debug Connection Test was moved from being a mode of the Connection Test run as a test, to being a standalone tool inside XJDeveloper or XJInvestigator. As a result, it was no longer possible to run XJEase functions before it to setup a board. In this release, there is now the ability to define Board Initialisation Functions that will be run before starting the Debug Connection Test or running the chain in XJAnalyser or the Analyser screen.

XJEase functions

XJTAG v3.2 allows the scope of functions to be set in the same way as variables. These changes to the compiler may mean that some code that was accepted without errors in v3.1.x may now trigger an error. We believe that all such cases are errors anyway – it was just that previous versions did not detect them as such.

Maintenance Licensing

With XJTAG 2.4.9, the system now checks the maintenance status of the XJLink, and will not allow XJTAG releases available after maintenance has expired to run.

Supported Platforms

XJTAG is supported under Windows XP^® (service pack 3 or higher), Windows Vista^® (both 32 bit and 64 bit), Windows 7^® (both 32 bit and 64 bit) and Windows 8^® (both 32 bit and 64 bit). Please upgrade to one of these operating systems before attempting to install XJTAG, and then apply the latest Service Pack for your operating System. Service Packs are available from the Microsoft Support website.

Support for Windows 2000 was dropped in version 2.4.

XJTAG recommends a screen resolution of at least 1024×768.

Target Hardware

In order for XJTAG to interact with a circuit, the JTAG chain must be set up properly. To help with this, we have a produced a set of DFT guidelines. There is also a troubleshooting section in the help files.

Side-by-side installations

It is only possible to have one instance of each major release of XJTAG installed. It is possible, for example, to install any variant of version 2.5.x along side any variant of version 2.6.y; however it is not possible to install two variants of version 2.5, e.g. 2.5.6 and 2.5.7.

In order to allow users of the XJRunner COM interface to upgrade XJTAG without having to recompile their applications, the GUID for this component of XJTAG does not change with each major version of XJTAG.

Consequences: To use the XJIntegration COM object in side-by-side installations the correct version of the library must be selected when switching between versions. The Version Checker utility (XJVersion) that comes with XJTAG allows the registered version of the XJIntegration to be switched between installed versions.

Changing Project File Associations

By default, double-clicking on an XJTAG project file of any kind will open it in the most recently installed version of XJTAG. The Version Check utility (XJVersion) can be used to control these file associations. It is recommended to do this using the copy installed with the latest version of XJTAG that you have installed.
